mock HttpContext.Current.Server.MapPath using Moq?

Question

im unit testing my home controller. This test worked fine until I added a new feature which saves images.

The method that’s causing the issue is this below.

Answer 1

Below works for me.

string pathToTestScripts = @"..\..\..\RelatavePathToTestScripts\";
string testScriptsFolder = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, pathToTestScripts);

var server = new Mock(); // Need to mock Server.MapPath() and give location of random.ps1
server.Setup(x => x.MapPath(PowershellScripts.RANDOM_PATH)).Returns(testScriptsFolder + "random.ps1");

var request = new Mock(); // To mock a query param of s=1 (which will make random.ps1 run for 1 second)
request.Setup(x => x.QueryString).Returns(new System.Collections.Specialized.NameValueCollection { { "s", "1" } });

var httpContext = new Mock();
httpContext.Setup(x => x.Server).Returns(server.Object);
httpContext.Setup(x => x.Request).Returns(request.Object);

YourController controller = new YourController();
controller.ControllerContext = new ControllerContext(httpContext.Object, new RouteData(), controller);
